Development of a Novel Grinding Process to Iron Ore Pelletizing …
As far as the pelletizing process is concerned, particles at solid phase (which is the mixture of ore fines, additives, and binders) need a liquid phase (water) for a sustainable intergranular network. Furthermore, water plays an important role in the agglomeration and has a direct influence on green pellets plasticity.
